“…Numerous of scientists have been concerned with this issue. Chen and co-workers [84] were the first that included a simple analytical model in their beam formulation to account for the effects of local buckling of circular cross-section. Since then a lot of research efforts have been dealt with buckling including shear lag and distortional effects in the concept of a beam theory.…”

Comparing Euler-Bernoulli or Tismoshenko beam theory to higher order beam theories, an essential difference can be depicted: the additional degrees of freedom accounting for out-of plane (warping) and in-plane (distortional) phenomena leading to the appearance of respective higher order geometric constants. In this paper, after briefly overviewing literature of the major beam theories taking account warping and distortional deformation, the influence of distortion in the response of beams evaluated by higher order beam theories is examined via a numerical example of buckling drawn from the literature.

“…This very important topic is addressed, for example, in papers by Sohal and Chen (1988) and Zuyan and Zhang (1991), both concerning box-shaped beam-columns. The behavior of beam-columns of cold-formed steel shapes is discussed in Chapter 14 of this guide.…”

“…Furthermore, a significant number of experiments have been performed to determine strength and deformation of steel tubes and pipes, motivated by offshore pipeline applications; bending tests on small-scale scale specimens have been reported by Reddy [14] and Kyriakides and Ju [15], whereas Gresnigt and Van Foeken [16] performed bending tests on four UOE and seamless 20-inch-diameter tubes. In addition to the above tests, analytical investigations on the ultimate capacity of tubular members have been reported by Toma and Chen [17], Sohal and Chen [18], Wagner et al [19], using a simplified analytical methodologies whereas more rigorous results on beam-column behavior have been reported by Karamanos and Tassoulas [20], using a special-purpose numerical technique.…”

The structural resistance of high-strength steel seamless tubular beam-columns of circular cross-section subjected to axial compression and bending loading is investigated, using experimental testing and numerical finite element simulations. Experiments on short and slender seamless tubular specimens are conducted, and simulated with rigorous finite element models. Prior to experimental testing, initial imperfections and residual stresses are measured, and the measurements are taken into account in the numerical models as initial conditions. Α good comparison is achieved between numerical simulations and experimental results in terms of ultimate strength capacity. Using the finite element tools, parametric numerical analyses are conducted under combined axial-bending loading conditions. First, the influence of initial imperfections (wrinkling) on the structural behaviour of high-strength steel tubular members is examined, in terms of their cross-sectional strength. Subsequently, stability curves for axial compression, and thrust-bending interaction diagrams for the highstrength steel tubular members are obtained. The cross-sectional strength, the stability curves and the interaction diagrams obtained numerically are compared with existing relevant provisions of European and American specifications (ΕΝ 1993, ΑΡΙ RP 2Α and AISC) for the design of beam-column tubular members. The comparison shows that the provisions of those specifications, originally developed for mild steel CHS members, result in reasonable, yet conservative, predictions for the structural resistance of high-strength steel seamless CHS members. It is also suggested that significant improvement of EN 1993 predictions can be achieved revising the classification of high-strength steel CHS sections.
